Slow booting on SKR V1.3 #481

Closed mrx23dot closed 3 years ago

mrx23dot commented 3 years ago

There is a 5-6second delay before Marlin's setup( ) is called, so I think it comes from the bootloader. It's also there without SD card inserted.

Is it possible to remove this delay? Why is it there? Where can I find the source code for the bootloader? Why isn't in this repo?

https://github.com/Marsman1970/SKR-V1.3-Bootloader only contains the original (ripped) bootloader binary, without source code.

@bigtreetech please upload the bootloader source or fix the issue.

Isn't that enough for you?
